Anti-Tuning: Updates for Shimano and Bosch

badassBox 4 Shimano 2019 and Shimano motor with Nexus Di2 hub gears

As we were recently confirmed, the tuning of a Shimano engine together with a Nexus Di2 hub gear (5-speed, e-bike specific) is no longer possible.

The tuning will probably be recognized based on a plausibility check and then it is no longer possible to change gears and the gear indicator disappears from the display.

badassBox 4 Bosch and Bosch Active Line Plus

Recently we received a message from our network that the Bosch Active Line Plus engine of an affected e-biker was tested positive for tuning and limited to 18km/h after a firmware upgrade in the workshop.

This was not our badassBox 4 but a wired tuning product, which was removed and reinstalled before the workshop date.

What makes this incident interesting, however, is the fact that the anti-tuning measures apparently only came into effect with a new firmware upgrade.

This supports our fear that so far the latest generation of engines will initially work with tuning and that anti-tuning measures could only be applied retrospectively or with a time delay.

With the current state of knowledge, we can only advise against buying an e-bike with a new Bosch motor (Gen. 4 or Gen. 3 Active Line (Plus)) or urgently refrain from getting a new firmware.

badassBox 4 Bosch for model year 2020

For the Bosch engines of model year 2020, Bosch had announced that it would completely eliminate tuning. As things stand today, we cannot agree with this statement.

Our current badassBox 4 also works with Bosch MY 2020 engines. We have tested it with the Performance Line CX and the current firmware So far, no functionality has been found that differs from the previous generation of engines.

But: what still works today with the firmware version mentioned, cannot work tomorrow with an update of the firmware. Therefore...

Caution with Firmware Updates

The firmware of the motors and other electronic components are essential components of the overall e-bike package. The updateability of the components allows manufacturers to influence the functionality of your e-bike long after the purchase of the e-bike.

In the ideal case, the firmware update is only used to correct errors in the software. In the far more common case, the e-bike buyer is provided with new functions that promise good things but can also bring a lot of bad things with them.

Even without always installing the latest firmware with the relevant apps from the manufacturers yourself, there is the danger of catching new functions every time you visit a workshop. Some manufacturers encourage dealers and specialist workshops to install the latest firmware on the e-bike every time you show up at the workshop. Mostly and gladly also without concrete previous knowledge of the customer. This can lead to user data being read out and new functions being implemented, e.g. against tuning.

Therefore we still recommend our customers not to carry out any upgrades/updates of the motor firmware or to have them carried out if there is no need for them.

A working, tuned e-bike with an older firmware is always better than an e-bike with the latest firmware, which is restricted to 25km/h.

Badass Gravel-E-Bike

We are happy to present our third e-bike prototype to you in time for the Eurobike, which is currently taking place in Friedrichshafen and where gravel plays a very important role:

the badass Gravel e-bike.

Thanks to the light carbon frame with tire freedom up to 700x50C and the Polini E-P3 motor with 250W power and 500Wh battery it weighs only about 15kg ready to ride and can guarantee with its agility and power riding fun on all surfaces.

Equipped with SRAMs 1x12 Force AXS gears / brakes and XO1 AXS rear derailleur and cassette (10-50T), the bike always offers a suitable ratio on any terrain, from road to single track. Thanks to the precision and speed of the AXS, every gear change is a pleasure. The 160mm discs at the front and rear reliably decelerate the bike even on fast asphalt gradients.

Due to the low weight and the hardly existing friction loss in the engine, the Gravel-E-Bike rides almost like a conventional Gravel-Bike and is also beyond the 25 km/h limit very economical to move. Thanks to the lightweight equipment with Fizik Antares saddle, 3T Superghiaia carbon handlebars and the easy to use and informative Polini display, it can be relaxed and sporty on the road. All cables are routed internally for optical and aerodynamic reasons and the cockpit is fully integrated. For the icing on the cake, we have installed the Omata One bike computer on the prototype and an Apidura saddlebag for transporting your belongings. With the two fastenings for bottle holders and the mounting points for mudguards, year-round use is also guaranteed.

On the first test drives the Polini engine could convince with its sheer power and efficiency. Although most of the time you are "too fast" on the plain to benefit from the support, the engine is even more enthusiastic on inclines. The five support levels can't be used to the full, even on ascents in the 14% range. Already in the fourth level you run the risk of tearing the 25 km/h limit. Based on previous tests, a range of loosely over 100km at 2000Hm can be certified quite safely. Polini even gives a theoretical range up to 200km in the plain.

With the fitted Gravel tyres WTB Riddler in 700x45C you are in good hands on asphalt, all kinds of field, forest and meadow roads and even on moderate single tracks. They convince with low rolling resistance and plenty of grip, while at the same time offering good puncture safety.

Even though the appearance and geometry are quite sporty, the E-Bike is still ideal for relaxed, fast commutes, for extensive rides over mixed terrain and also for a small training lap. If you use the engine support sparingly, you could even dare a small bikepacking trip with it. Or in short, except for downhill or otherwise very rough terrain, the Gravel E-Bike can be easily moved anywhere and at any time.

So far it is only a prototype, but we are completely convinced that this e-bike would be a real enrichment for many people. Whether we finally produce the bike... we'll see.

New badassBox 4 Shimano 2019


With the firmware update to version 4.7.0 (for the E8000 engine) Shimano had limited the function of our badassBox on the software side at the beginning of June.

Today we can announce that with our new badassBox 4 Shimano 2019 we were able to restore compatibility with the following firmware versions:

E8000: Version 4.7.0
E7000: Version 4.4.0
E6100: Version 4.4.0
E5000: version 4.1.0

On the other hand, we have modified the functionality of the electronics so that there is now only one badassBox for mechanical and electronic shifting (Di2), which works with both.

Here you can buy the badassBox 4 Shimano 2019:

We also recommend that our customers do not upgrade or have upgraded their motor firmware if there is no need to do so.

Badass Allmountain-E-Bike

Today we present you another e-bike prototype from us:

The official Badass Allmountain-E-Bike.

It is based on a lightweight carbon frame and is equipped with a Bafang M500 motor with 250W power and 95 Nm torque. The motor is powered by the 450Wh battery and the wheel weighs only 21kg ready to drive, which is a very acceptable value for an E-Fully with these performance values.

Even though even lighter components could still produce less than 20 kg, we have explicitly decided not only to use the lightest (and therefore most expensive) components, but also to achieve the "best-bang-for-the-buck" in the overall package.

Equipped with SRAMs 1x8 EX gear (36T chainring and 11-48T cassette) and SRAM Guide RSC brakes (front 203mm, rear 180mm), the bike offers the right gear ratio on any terrain and decelerates reliably on any gradient. The supposedly wide spread of the gears is compensated by the engine power, which is why eleven or more gears lose their sense.

To maintain grip and damping in rough terrain, we use a Fox 36 Factory suspension fork with 150mm travel in the front. At the rear there is a Fox CDT LV damper, which we don't consider to be the first choice, but surprisingly it works very harmoniously. All this in combination with the Michelin Wild AM 27.5" x 2.6" tires makes the toughest rides a relaxing pleasure.

The first test rides were impressive, the engine supports with a lot of power in all situations. You might call the characteristic "oldschool", but when you start you get a direct feedback from the engine in the form of vehement bang.

Since the battery is big enough, there are enough reserves even for longer trips, but - and without previous tests for the maximum running time - the bike is not yet an endurance runner and after about 50 - 60 km you are confronted with an empty battery. Even if the bike remains rideable thanks to low pedaling resistance, the joy disappears quite quickly, which is due to the weight and rolling resistance of the tires.

If the bike is used in an appropriate way, it is a lot of fun and with a price of 6000 - 7000 € you don't have to hide from the established competition.

But it is still - as it was the case with our Aero-Allroad-E-Bike - only a prototype. A series production is uncertain and if so, then still in some distance.

As you can easily see, there are some components that are still missing (e.g. a dropper seat post) or that could be discussed (an upgrade for the rear shock).

Now you are asked: what would you like to see built into this Allmountain?

Give us feedback, maybe it will soon become reality.

Badass Aero-Allroad-E-Bike

We are happy to show you a first in-the-wild preview of our first e-bike prototype.

To describe it, let's call it badass Aero-Allroad-E-Bike.

Thanks to the carbon frame and the Bafang M800 motor with 200W power and 200Wh battery it weighs only about 13kg ready to ride what we would call really "lightweight" for an e-bike.

Equipped with SRAMs 1x12 Force AXS shifters / brakes and XO1 AXS rear derailleur and cassette (10-50T), the bike offers the right gear ratio on every track.

Thanks to the low weight and the hardly noticeable friction loss in the engine, the e-bike rides more like a bio-bike and is very economical even beyond the 25km/h limit.

The first test drives were absolutely amazing, the engine supports pleasantly on the climbs and is otherwise largely unnoticeable. Because you are "too fast" most of the time and the motor only supports you on slopes, the 200Wh of the battery isn't half as bad as you might think from the bare number. In the tests so far, a range of 80km at 800Hm can be attested quite safely.

With the cyclocross tires currently being tested in 700x32C, the term "allroad" even extends to tracks that can no longer be described as roads at all.

Even if the maximum tire width is limited to 32 mm, you can still be confident about entering the gravel range. With less profiled tires, perhaps only 28 mm wide, road-oriented use is certainly even more exciting. We will try that out very soon.

Even though its appearance and geometry are quite sporty, the e-bike is still ideal for relaxed, fast commutes, extensive rides over mixed terrain or just for a small training lap (with the engine switched off, it rides like a racing bike with five kilos overweight).

But so far, it's just a prototype. Whether we will produce the bike is far from being decided, certainly the concept is not suitable for the masses and will only inspire a small circle of cyclists. However, we have been fully convinced so far.

Upgrade warning Shimano

Subject: Shimano E8000 firmware 4.7.0


Through our own tests - and also through customer information - we have determined that the firmware 4.7.0 for the Shimano E8000 engine impairs the functionality and effect of the badassBox. This applies to versions with electronic gearshift (DI2) as well as to mechanical gearsets. The motor support stops and the error message "W011" is displayed.

Therefore, we recommend our Shimano customers not to upgrade to firmware 4.7.0 at this time in order to keep the option for tuning/original state.

The operation of the eBike without badassBox is possible without restrictions.

For upgrades already carried out, it may be possible to downgrade the firmware to the 4.6.0 version. Please consult Google with the search term "shimano firmware downgrade" and you will probably find what you are looking for.

Since we as manufacturer of contactless and temporary tuning stand for the freedom of choice between legal conformity for the operation in road traffic and tuning, we will continue to try to find a solution also for the new firmware generation.

Unfortunately, firmware updates are at the same time also a gateway for their unwanted features, in spite of the manufacturers' praising of new features, better battery management etc.

Therefore we generally advise not to install updates immediately, but to wait for reports on "incompatibilities". The larger manufacturers will certainly continue to try to take away or limit your choice of tuning.

Since we don't know future developments in this area in advance, we can only react when the time comes. Therefore our recommendation is to handle upgrades carefully or not to upgrade at all.

In general, only the buyer has the choice to consider which engine manufacturer he will trust in the future with regard to the choice of tunability before making a purchase.

badassBox 4 for Specialized


Although Specialized uses the very veritable Brose engines (Turbo Levo: Brose S Mag and Turbo Kenevo: Brose S) in their eBikes, for which the normal badassBox 4 Brose is used, the positioning of the sensor requires the use of a universal mount adapter. With the new Turbo Levo MY19 another step is necessary due to the discreet positioning in the dropout and the sensor shape, the use of our special Specialized-Turbo-Levo-Adapter.

Therefore we now have the badassBox 4 Specialized Set and the badassBox 4 Specialized Set Turbo Levo 2019 in our program for all Specialized riders.

For the price of 154,- EUR (instead of 161,80 EUR in unit prices, plus shipping costs) the Specialized Set includes the badassBox 4 Brose, a spoke magnet with Toolfree 4mm as well as the Universal Mount Adapter for moving the sensor.

The badassBox 4 Specialized-Set Turbo Levo 2019 has the same scope as the Specialized-Set, but instead of the Universal-Mount-Adapter includes the Specialized-Turbo-Levo-Adapter, and costs 159,- EUR (plus shipping costs).

With the help of these simple instructions the one-time conversion is quickly done and the Turbo Levo also gets the full enjoyment of the badassBox 4.

badassBox 4 for Fazua


Last but not least, we now also offer our badassBox 4 for Fazua engines.

At a price of 149,- EUR plus shipping costs the badassBox 4 has some significant improvements. In addition to the use of an AAA battery instead of the lithium CR2 battery from our previous models, the width has also been significantly reduced (from 20.5mm to 14.5mm - almost 30%), so no adapters are needed for mounting.

The badassBox 4 uses our patented FEET (Field Enhancement & Elimination Technology) which allows an even longer operating time (now 7000km) despite the lower energy content of the AAA battery compared to the CR2 cell. The also patented snap lock not only eliminates the O-ring but also allows an even faster and easier assembly and disassembly of the badassBox with only one hand.

Following the badassBox 4 for Bosch, Shimano, Yamaha, Panasonic, Brose, Kalkhoff-Impulse, Conti and Pendix, Fazua's engines now also benefit from the new technologies for the first time.

Antituning on the wrong track

If one observes the development of the last years in the eBike market, then one can determine a clear tendency: More and more gimmicks are being used as arguments for ever higher prices. The customer has at most a disproportionate added value. He's all about fun and for some people speed is part of the fun. With the planned anti-tuning measures this fun on the part of the manufacturers is to be prevented.

The arguments of the industry seem very constructed to us, since a tuned eBike does nothing that a well-trained rider can't do without an engine. So why do they make such a fuss? Well, the question could easily be answered if one looked at the obvious consequences and their profiteers. S-Pedelecs are more expensive and insured.

It is obvious that the e-market is facing a new regulation. This has nothing to do with tuning, but with the fact that it has become a mass market and new eMobiles are coming onto the market at ever shorter intervals, from ePedal-Scooter to eSkateboard to eScooter, to name but a few examples. The sheer number alone creates a possible need for action. We described in the previous entry how to do this for sportive eBikes. Other options seem to serve only the desire of the industry and not that of the customer.

A proposal for the legalization of eBike Tuning

Our official badassGirl Chiara

Our official badassGirl Chiara

First of all, you have to realize that our customers want to tune. They want to go faster. They want to decide for themselves when and how to use their eBike. Otherwise we wouldn't exist.

eBike manufacturers fear that an increase in tuned eBikes will have negative consequences for their industry. We do not know the exact motives, we suspect that the bicycle industry does not want to endanger its historically founded special position in road traffic or for recreation in nature, and therefore - quasi in anticipatory obedience - seeks to join forces with legislation.

The legislator has actually little reason for a new regulation, especially with regard to the manifold, complicated and costly consequences. Even a takeover of the American system (usually a 20 mile/ 32km/h restriction, higher continuous power) would not solve the problem and would hardly produce less effort.

A pragmatic solution could be to extend the law by means of a legislative process, in a sub-paragraph, with a kind of special permission for tuned eBikes. The following criteria would then have to be met: Use only outside built-up areas and only on unpaved roads. Furthermore, an insurance which we would like to sell with every badassBox - after all, this device is the one that creates the situation first - and is linked to the serial number of the badassBox. With the badassBox tuning measure removed, the pedelec must be completely legal for use on the road again and must be clearly recognisable as tuned when the badassBox is fitted.

In this picture, everyone involved would benefit, why should that not be possible? Please like us on Facebook if you think we should submit a petition for it.

badassBox 4 now also for Yamaha!

For Eurobike 2018 we will introduce badassBox 4 for Yamaha with an introductory price of EUR 139,- + shipping costs! The offer is valid for week 28, Decisive is the date of purchase. After that we set our badassBox 4 to 149,- EUR + shipping costs.

badassBox 4 has some significant improvements. Besides the use of an AAA battery instead of the Lithium CR2 from our previous types, the overall width has also been significantly reduced (from 20.5mm to 14.5mm - just under 30%). badassBox 4 uses our patented FEET (Field Enhancement and Elimination Technology) which, despite the lower energy content of the AAA battery compared to the CR2 cell, allows an even longer operating time (now 7000km). The patented snap lock not only eliminates the O-ring but also enables even faster and easier assembly and disassembly of the badassBox with only one hand.

badassBox 4 is manufactured in the laser sintering process from high-quality PA11 Black, which makes a matt, almost velvety, surface in very dark black anthracite possible. This with extreme impact strength and very high elongation at break. The elongation at break for injection moulded ABS parts is approx. 5% for PA11 at 45%! PA11 is obtained from castor oil and passes the cytotoxicity test according to DIN EN ISO 10993-5.

badassBox 4, like all our products, is completely manufactured in Germany. With an even better potting compound we increase the structural strength of the badassBox while the electronics are still completely insensitive to moisture. Double quality control of all our devices, availability of spare parts even for older versions as well as our well-known good service are a guarantee for a long and satisfied use of our badassBox on your eBike.

badass kicks ass with it´s new FEET (Field Enhancement & Elimination Technology)

These two small, inconspicuous magnets in the spoke-facing head of the badassBox have a significant effect. They build up a weak magnetic field above the sensor, so that the amount of energy required to switch the sensor is significantly reduced. The polarity of the spoke magnet is important for this, which is why we supply a spoke magnet for most motor systems. This makes it possible to achieve a higher mileage of the badassBox with an AAA battery instead of the previous Lithium CR2. This despite the fact that lithium cells have up to five times more energy! By using the narrower battery, the width of the badassBox decreases, so that our new badassBox 4 only builds up a few millimeters on the sensor.

badass FEET is currently offered for our badassBox 4 for Panasonic and Shimano. When the last tests have been completed, the badassBox 4 will also be available for other engine systems. We ask for your indulgence if we do not want to give a fixed release date at the moment.

eBike Tuning, the relevant differences between temporary and permanent tuning

...on private property.

...on private property.

The term eBike Tuning, currently concentrates on components that move the 25km/h restriction of pedelecs upwards. This is prohibited by law. We distinguish two fundamentally different classes of tuning: firstly permanent tuning measures and secondly temporary tuning measures. They can be recognized by the time required for installation or removal of the measure.

Permanent tuning measures are those that remain on the eBike or can only be removed with effort or even tools. This includes software solutions as well as cable kits. With these solutions, it is usually still possible to switch the measure on or off. This possibility is irrelevant for the legal offence, since the modification on the eBike is permanent and verifiable. Whether software, cable kit or unplugged dongle are detected makes no difference. The permanent modification even implies a deliberate intention to deceive.

When it comes to temporary tuning measures, our badassBox should be mentioned above all. As the first manufacturer of this kind of tuning we decided very early and consciously to offer only one solution. A solution that clarifies a discussion about the existence of a tuning from the outset. If the badassBox is mounted, the eBike was operated without speed lock. If the badassBox is not mounted, the eBike is in its original condition.

The advantage of the badassBox is also its disadvantage. Because you transmit an incorrect speed to the speed sensor of the motor system without contact, so to speak from the outside - the speed is also displayed incorrectly. The values derived from this speed, such as range and total kilometres, are distorted. However, we find that this fact is a small price to pay for the benefits of the badassBox. Most people already have a GPS device in their pocket. Other solutions involve technical risks (e.g. damage during installation on cables, mechanics or electronics). Above all, however, it should be emphasised that the user with the badassBox has the choice of where to use his eBike the way he chooses.

If you would like to try out the badassBox, please follow the link to our website below. We offer a 3 month money back guarantee, if the measure does not suit you, send us the badassBox with a copy of the invoice, also used, and get your money back. No questions asked, no risk to take.

The badassBell from swisstrailbell, of Swiss production

Little is more unpleasant than driving onto pedestrians or hikers from behind. One does not want to frighten anyone and both ringing and shouting or whistling is unpleasantly frightening to the foot people. Consideration is important and so a solution was needed for this situation!

We found something ideal here: A sheep belly from Switzerland that can be easily and securely attached to the handlebars with Velcro. Here someone has thought along and made sure that nothing is scratched thereby also. A magnet sewn into the fabric tape can be detached from its fastening position with one hand and easily cut under the little bell so that the bobbin is secured and switched off. Even after the hardest pothole, nothing can still be heard. When the magnet is reattached to its mounting position, a clear ringing can be heard at each vibration. It reminds of an Alpine cattle drive with a slightly higher ring tone.

Of course, we tested the product extensively and found the reactions from pedestrians extremely positive. Apparently the sound is also perceived very well by older people and by the constant ringing during the start-up the participants can estimate very well how fast the eMTB is approaching. A friendly hello at moderate speed is then also gladly answered. Top!

Now, of course, we are not a bell manufacturer. When we read about the social commitment of the manufacturer, this product clearly belonged to us in our shop. It is the ideal addition for any considerate rider and connoisseurs will immediately understand with the printed badass eBikes logo that there is a wolf in sheep's clothing.

About physics and real speed

If you have always wondered how fast you can really ride with eBike Tuning, you are invited to try our speed performance calculator on

General answers are not possible, because the achievable speed depends on some variables. Physics can provide a relatively rough estimate of the interrelationships. Our online calculator, adapted by, clearly shows the achievable speed depending on the power input or vice versa the necessary power for a certain target speed. The power is assumed to be the power of the overall system, i.e. eBike plus driver.

Anyone who has ever done an exercise ECG may know how hard it is to kick 400W. The 650W reached with it are not even enough for 45km/h.
